I have a question for those of you familiar with the UPC.
1. Can a horizontal drain be turned to vertical using a 45(1/8th) bend, a 1′ piece of pipe, and another 45?
I am trying to get the drain line through the ceiling and into a wall utilizing a void from a soffit. Due to HVAC equipment I am unable to use a typical 90 turn at the top plate to make the drop. Any help would be appreciated. Thanks, David.
